Energy to place satellite in orbit—M . “NASA launched a $195 million astronomy satellite at the weekend to probe the enigmatic workings of neutron stars, black holes, and the hearts of galaxies at the edge of the universe . . . The long-awaited mission began at 8:48 a.m. last Saturday when the satellite’s Delta–2 rocket blasted off from the Cape Canaveral Air Station.”13This “X-ray Timing Explorer satellite” was reported as having a mass of 6,700 lbm and being placed 78 minutes after lift-off into a 360-mile-high circular orbit (measured above the earth’s surface). How much energy (J) went directly to the satellite to place it in orbit? What was the corresponding average power (kW)? The force of attraction between a mass m and the mass Me of the earth is GmMe/r2, where r is the distance of the mass from the center of the earth and G is the universal gravitational constant. The value of G is not needed in order to solve the problem, as long as you remember that the radius of the earth is 6.37 × 106 m and that g = 9.81 m/s2 at its surface.
